One thing has become very obvious over the last few years: the Yankees value having a left-hander in the bullpen. Two, preferably. Some teams don’t worry too much about carrying a southpaw, but not these Yankees. Joe Girardi likes to have a matchup lefty out there and the team has spent a lot of money trying to fill that spot. Remember Damaso Marte and Pedro Feliciano? Of course you do.

The 2014 season were no different, but, believe it or not, they only had 109 appearances by a left-handed reliever this year. That was the fifth fewest on baseball. At the same time, they had 56 lefty appearances of two or fewer batters faced, the fourth most in baseball. Girardi is definitely a fan of matching up for a batter or two if the opportunity presents itself. Let’s review the team’s surprisingly large collection of left-handed relievers from this past season.

Matt Thornton

The Yankees signed the 38-year-old Thornton to a two-year contract worth $7M last season, figuring he could still be a quality specialist even though his performance against righties had declined big time in recent years. He was one of the top relievers in the game regardless of handedness not too long ago. Maybe there was still some magic in there.

Thornton threw only 24.2 innings across 38 appearances with New York, so Girardi definitely used him as a matchup guy. His overall 2.55 ERA (2.73 FIP) is good but that’s not the best way to evaluate a lefty specialist. Thornton held same-side hitters to a .237/.306/.250 (.258 wOBA) batting line with a 17.2% strikeout rate, a 3.1% walk rate, and a 54.3% ground ball rate. Despite still having mid-90s heat, his swing-and-miss rate against lefties was a paltry 8.3%. That’s well-below-average. Also, he allowed 14 of 43 inherited runners to score (33%), including five of the last 12.

In early-August, the Yankees simply gave Thornton away for nothing. The Nationals claimed him off revocable trade waivers and New York opted not to pull him back, so they let him to go Washington on the claim. It was … weird. Girardi and Brian Cashman both confirmed the move was made to create roster and payroll flexibility. Thornton had a 0.00 ERA (2.51 FIP) in 11.1 innings for the Nats after the claim and quickly emerged as an important part of their bullpen.

The Yankees spent the first ten or so weeks of the season cycling through some amazingly bad long relievers, so, when the Giants decided to cut ties with Huff in mid-June, the Bombers jumped at the chance to re-acquire him. The minor trade cost New York nothing but cash.

Huff, 30, had a 6.30 ERA (4.38 FIP) in 20 innings for San Francisco, but he actually pitched pretty well in pinstripes. He chucked 39 innings across 30 appearances — so he was multi-inning guy, not a specialist — and posted a 1.85 ERA (4.00 FIP), holding lefties to a .250/.301/.279 (.266 wOBA) batting line with a 19.2% strikeouts rate and a 6.2% walk rate. Huff also stranded 16 of 17 inherited runners. What more do you want from a low-leverage lefty?

After letting Thornton walk, the Yankees grabbed Hill off the scrap heap and he actually had two stints with the team. He came up in early-August, made six appearances, was designated for assignment, then was called back up when rosters expanded in September to make eight more appearances. All told, Hill faced 19 lefties with New York, striking out seven, walking two, hitting one, and allowing four hits. That’s a .250/.368/.250 (.298 wOBA) batting line. At one point in September he struck out six in a span of eight batters faced.

Hill was designated for assignment in late-August to make room for Outman, who the Yankees picked up from the Indians because he was a so very slight upgrade. He faced ten left-handed batters in pinstripes and held them to one hit. He also struck out one. That works out to a .100/.111/.111 (.099 wOBA). If you extrapolate that out over 60 innings, Outman was, like, the best lefty reliever ever, man.

Cesar Cabral

Two years ago, Cabral almost made the Opening Day roster as a Rule 5 Draft pick before suffering a fractured elbow late in camp. He made four appearances with the Yankees this season and faced five lefties. One made contract (a hit), one drew a walk, one was hit by a pitch, and two struck out. As you may recall, Cabral allowed three runs on three hits and three hit batsmen in one ugly April outing against the Rays. He was designated for assignment after the game, eventually landed back in Double-A, and that was that.

Confession: I totally forgot Jeff Francis was a Yankee. They acquired him in a very minor trade with the Athletics when they were desperate for pitching depth at midseason, and he somehow made not one, but two appearances in pinstripes. He threw a scoreless 14th inning in a late-July game against the Rangers — when Chase Headley hit the walk-off single in his first game with the team — and allowed a run in two-thirds of an inning against the Blue Jays a week later. They dropped Francis from the roster soon thereafter.

Wade LeBlanc

I did remember that LeBlanc was a Yankee this year! He made one appearance with the team. It went single, single, grounder to first, intentional walk, hit batsmen to force in a run, sac fly, ground out. The Yankees designated him for assignment to make room for Huff a few days later. I hope Wade LeBlanc goes into the Hall of Fame as a Yankee.

In the video above, Jim Callis and Jonathan Mayo chat about some of the Yankees prospects playing in the Arizona Fall League this month. Here is Callis’ companion piece with more on each prospect. Also, 1B Greg Bird was named the AzFL Player of the Week last week and Matt Eddy says LHP Cesar Cabral has elected free agency. He’s no longer with the organization.

Even though it is not really the halfway point of the season, there is no better time to review the first half than the All-Star break. This week we’ll hand out some simple, straightforward, and totally subjective grades, A through F, for the catchers, infielders, outfielders, rotation, and bullpen. We’ve already covered the catchers, infielders, outfielders, and rotation, so now let’s wrap up with the bullpen.

So maybe replacing Mariano Rivera won’t be so difficult after all. Robertson inherited the closer’s job — to the dismay of more than a few — and has run with it, pitching to a 2.76 ERA (1.73 FIP) in 32 appearances and 32.2 innings. He is 23-for-25 in save chances with a career best strikeout rate (16.26 K/9 and 44.7 K%) and a career best ground rate (51.6%) while keeping his walk rate (2.76 BB/9 and 7.6 BB%) in line with the last two years. Robertson is also holding opponents to a .198 batting average, second lowest of his career (.170 in 2011) despite a career worst .356 BABIP.

Robertson has allowed ten earned runs this year with five coming in one disaster outing against the Twins on June 1st. He has allowed one run while striking out 27 of 56 batters faced since. Overall, 59 of 98 outs this season have been strikeouts, including 58 of 89 (65.2%) since coming off the disabled list (groin) in mid-April. No pitcher who has thrown at least 30 innings this season has a high strikeout rate. It’s not even close, really. Robertson leads in K/9 by more than one full strikeout and in K% by roughly three percentage points. He’s been dominant in every sense of the word.

The Yankees will need Robertson to continue his dominance in the second half for obvious reasons, though his looming free agency will be hanging over everyone’s head. The two sides have not discussed an extension but that could change at any time. Relievers like Robertson — super high strikeout pitchers with proven late-inning/big market chops and no history of arm problems — are rare and the Yankees should make every effort to keep him beyond this season. If his work this year doesn’t convince them he is the man to replace Rivera long-term, then I’m not sure they’ll ever find someone good enough.

Just a few short months ago, Betances had a win a roster spot in Spring Training. Now he’s an All-Star high-leverage reliever who is 1996 Rivera to Robertson’s 1996 John Wetteland. Betances has a 1.46 ERA (1.37 FIP) while ranking third among full-time relievers in innings (55.1) and first in both fWAR (2.1) and bWAR (1.7). His strikeout rate (13.66 K/9 and 40.8 K%) is a bit behind Robertson’s but still among the highest in the league. He’s also stopped walking dudes (2.60 BB/9 and 7.8 BB%) and is getting grounders (50.5%).

Joe Girardi has not been shy about using Betances for multiple innings given his history as a starter — Betances has recorded at least four outs in 25 of his 40 appearances and at least six outs 12 times — though he did take his foot off the gas right before the All-Star break because it did appear the big right-hander was starting to fatigue a bit. His stuff was still electric but not quite as crisp. Hopefully the break recharges his batteries. A little more than a year ago, Betances looked like he may soon be out of baseball. The move into the bullpen has saved his career and given the Yankees a second elite reliever to pair with Robertson in the first season post-Mo.

From spot starter to swingman to trusted high-leverage reliever. Warren has had his role redefined over the last few seasons and he has now settled in as a quality third option behind Robertson and Betances. His numbers — 2.79 ERA (2.70 FIP) in 42 appearances and 48.1 innings — are not quite as good as those two, but he gets strikeouts (8.57 K/9 and 22.4 K%), gets grounders (46.8%), and is stingy with ball four (2.79 BB/9 and 7.3 BB%). His fastball velocity has also ticked up in short relief, averaging 94.1 mph this year after sitting 93.0 last year.

As with Betances, Girardi has taken advantage of Warren’s history as a starter by using his for multiple innings on several occasions — he’s recorded 4+ outs in 18 of his 42 appearances. The Yankees have said that if the need arises, they would pull Warren out of the bullpen and stick him in the rotation, but starters are dropping like flies and it hasn’t happened yet. Warren seems to have found a niche in short relief and he’s been a very valuable member of the bullpen despite being overshadowed by Robertson and Betances.

Shawn Kelley — Grade C

It was a tale of two first halves for Kelley, who opened the season as the regular eighth inning guy and nailed down four saves in four chances while Robertson was on the disabled list in April. He had a 1.88 (1.67 FIP) in his first 14.1 innings of the year before a disaster outing against the Angels on May 5th (two outs, four walks, three runs), after which he was placed on the disabled list with a back injury. It kept him out a month and he has a 4.05 ERA (3.21 FIP) in 13.1 innings since returning.

Kelley didn’t look right when he first returned from the back problem. He wasn’t able to finish his pitches and his trademark slider didn’t have much bite. It just kinda spun and floated. He looked much better in his last few outings before the All-Star break — one run, five hits, no walks, 13 strikeouts in 8.1 innings — and hopefully that’s a sign he’s now 100% and ready to take on some late-inning responsibilities so Girardi can spread the workload around. Definitely a mixed bag for Kelley in the first half.

Matt Thornton — Grade C

The rules of baseball fandom say we must hate the team’s lefty specialist, but Thornton has been solid (3.10 ERA and 3.04 FIP) in his 38 appearances and 20.1 innings. As his innings-to-appearances ratio suggests, Girardi has used him as a true matchup left-hander and not tried to force it against righties whenever possible. Thornton has held same-side hitters to a .229/.319/.244 (.262 wOBA) batting line with a 15.1% strikeout rate, a 3.8% walk rate, and a 50.0% ground ball rate. Solid.

The only real negative about Thornton is he doesn’t miss bats, even against left-handed hitters. That 15.1% strikeout rate is 76th out of the 90 left-handed pitchers who have faced at least 50 left-handed batters this year. Lefties have swung and missed only 20 times at the 220 pitches Thornton has thrown them this year (9.1%). That kinda sucks for a left-on-left reliever. Thornton missed a week with undisclosed soreness right before the break but did return to pitch against the Indians last week. LOOGYs, huh? Can’t live with ’em, can’t live without ’em.

Remember how awful Claiborne looked in Spring Training? We were talking about him as a candidate to be dropped from the 40-man roster if a need arose, but the Yankees kept him around and he pitched to a 3.57 ERA (3.82 FIP) in 17.2 innings while going up and down a few times in the first half. Three of his nine walks were intentional, uglifying his numbers a bit. Claiborne is currently on the Triple-A Scranton disabled list with a shoulder injury of unknown severity, which is not insignificant given his status as the team’s primary up and down depth arm.

The Yankees re-acquired Huff from the Giants in mid-June as part of their continuing efforts to find a not awful long man, and he’s since given the team 16.2 innings of 2.16 ERA (5.18 FIP) ball. Girardi used him as a matchup lefty while Thornton was out with his soreness and that predictably did not go well. Warren was pretty awesome by long man standards last year and that kinda spoiled us. Most long relievers stink. Is Huff keeping runs off the board? His ERA says yes. Has it been pretty? No but who cares. In that role you just want someone who can limited the damage and Huff has done that for the most part.

Did you realize Aceves threw the sixth most innings among the team’s relievers in the first half? I sure didn’t. The Mexican Gangster threw 5.1 scoreless innings in long relief in his first outing back with the team, but it was all downhill from there. He allowed 14 runs on 20 hits (six homers!) and four walks in his next nine games and 14 innings, putting his overall season numbers at 6.52 ERA (6.29 FIP) in 19.1 total innings. The Yankees designated Aceves for assignment in early-June, he accepted the outright assignment to Triple-A Scranton, and he was recently suspended 50 games after a second failed test for a drug of abuse. He will be missed by: no one.

The combined pitching line of these seven: 33.2 IP, 46 H, 36 R, 33 ER, 19 BB, 33 K, 6 HBP, 6 HR. That’s an 8.82 ERA and a 5.19 FIP in one more inning than Robertson has thrown this year. I didn’t even include Dean Anna. /barfs

Girardi has had to rely on his bullpen more than I’m sure he would have liked in the first half, mostly because of the rotation injuries. Yankees relievers have thrown 292 innings this season, the 13th most in MLB, though their 264 total pitching changes are only 23rd most. That’s because of guys like Betances, Warren, and Huff being used for multiple innings at a time.

The bullpen has a 3.85 ERA (3.60 FIP) overall, which is bottom third in the league, but they have a top-heavy relief crew with arguably the best setup man/closer tandem in the game. The late innings are no problem at all. The middle innings are where it gets messy. Kelley is the bullpen key to the second half to me — if he gets back to pitching like he did before his back started acting up, Girardi will have another trustworthy high-strikeout arm who could potential solve that middle innings problem.

The Yankees also announced that lefty Cesar Cabral has cleared waivers and been outrighted to Triple-A Scranton. He was designated for assignment the other day to make room on the roster for Matt Daley. Because he has been outrighted off the 40-man roster in the past, Cabral can elect free agency rather than report to Triple-A. I think he has three days to make that decision, but don’t hold me to that.

11:49pm: The Yankees just announced that Cabral has indeed been designated for assignment. Matt Daley was called up from Triple-A Scranton as the corresponding move. The Queens native had 13 strikeouts in five innings for the RailRiders.

11:43pm: Via Marly Rivera: Cesar Cabral was designated for assignment following tonight’s game. He failed to retire any of the six batters he faced tonight, including three hit batsmen. It was ugly.

There is no word on the corresponding roster move just yet, but it’s worth noting Danny Burawa threw 51 pitches last night and Mark Montgomery has pitched in each of the last two days. Fred Lewis and Al Aceves both pitched tonight as well. Not sure who is getting called up. Maybe Matt Daley? Here is our Bullpen Workload page for your perusal.

Tuesday: Cabral has officially been called up, the Yankees announced. Lots and lots of lefties.

Monday: Via George King: The Yankees are planning to call up left-hander Cesar Cabral to replace David Robertson, who was placed on the 15-day DL with a Grade 1 groin strain earlier today. Three lefties in the bullpen is not ideal, especially since two of them (Cabral and Matt Thornton) are pure specialists, so Vidal Nuno is going to have to take on some more responsibility. He figures to be asked to get both righties and lefties out now.

Depending on what happens with the fifth starter spot, the Yankees have either two or three bullpen spots up for grabs in camp. There are something like eight or nine relievers competing for those spots, though some obviously have a better chance than others. Dellin Betances and Cesar Cabral, both of whom pitched with the team last September, have already emerged as the early favorites for big league jobs just two weeks into the Grapefruit League schedule.

Betances, who turns 26 in less than two weeks, continued his strong spring yesterday by pitching around a one out double in an inning of work. He didn’t just pitch around the double, he did it by throwing six straight curveballs to big leaguers Matt Joyce (strikeout) and Wil Myers (ground out). That’s not something Betances would have been able to do in the past. Emphasizing his offspeed stuff is something he’s been working on this spring.

“I feel good right now. I feel good with where my offspeed is. I feel like I can throw it for strikes. It’s been working for me. I’m just trying to better myself with each outing,” said Betances to Bryan Hoch. “I know my offspeed was one of the things that helped me out when I got in trouble with my fastball. I would try to use that to keep myself a little calm with my mechanics. I just tried to take that into this spring, mix my pitches. In the big leagues, everybody can hit fastballs, no matter how hard you throw. I’m just trying to use all my pitches the best way I can.”

Betances is up to 6.1 scoreless innings in camp, striking out five against two walks and two hits. The opponent quality stat at Baseball Reference says he’s been facing mostly big leaguers, which isn’t surprising. He’s been the first guy out of the bullpen in most games. Betances has the size and power stuff the Yankees love, so maybe a roster spot was his to lose coming to camp following last season’s bullpen breakout. If it was, he’s done nothing to lose the spot. If it wasn’t, he’s pushed himself towards the top of the depth chart.

With Cabral, on the other hand, it always felt like he was on the outside of the bullpen competition looking in. At least it did to me. Carrying a second lefty specialist is a luxury, and with Matt Thornton already on board to be the primary guy, passing on Cabral to take a more versatile right-hander makes some sense. It still does, actually. Then again, the best pitchers are the best pitchers, and if another southpaw is one of the seven best relievers in the organization, he should be on the roster come Opening Day.

In 4.1 innings across four appearances this spring, the just-turned-25-year-old Cabral has allowed one hit and two walks, striking out four. Lefties are 0-for-4 with three strikeouts and a walk against him. Cabral has not faced the best competition however, basically Double-A level according to that opponent quality metric at B-Ref. He can only face the guys he’s put out there against though, and if he keeps getting outs and handling lefties, he’ll get a longer look and more serious consideration as camp progresses.

So far, after only a handful of Grapefruit League appearances, both Betances and Cabral have done everything they’ve needed to do to secure a big league bullpen job. Neither guy has a spot locked up of course, but they have moved to the front of the pack. Preston Claiborne, Matt Daley, and Fred Lewis have pitched well too, so they’re not alone, but others like Robert Coello and Brian Gordon have already managed to pitch themselves out of bullpen consideration. Both Betances and Cabral have made a nice little statement early on and put themselves in good position for a big league job when roster decision time comes.
